topic: update extensions metadata
Let us assign a version number to this release and add some more data about the
extensions.
Test script based on sharing.rst: ensure that all scenarios in that
document work as advertised.

To start things off, let's make one public, immutable changeset::
$ cd test-repo
$ echo 'my new project' > file1
$ hg add file1
$ hg commit -m'create new project'
$ hg push
pushing to $TESTTMP/public (glob)
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
and pull that into the development repository::
$ cd ../dev-repo
$ hg pull -u

requesting all changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
Let's commit a preliminary change and push it to ``test-repo`` for
testing. ::
$ echo 'fix fix fix' > file1
$ hg commit -m'prelim change'
$ hg push -q ../test-repo
Figure SG01 (roughly)
$ hg shortlog -G

Now let's switch to test-repo to test our change and amend::
$ cd ../test-repo
$ hg update -q
$ echo 'Fix fix fix.' > file1
$ hg amend -m'fix bug 37'
